LUDWIG SEVEBIN, OF HAGEN, GERMANY.

DEVICE FOR SECURING BELLS, GLOBES, GHIMNEYS, on THE LIKE TO LAMPS.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed September 2, 1913. Serial No. 737,721.

To all whom it may concern Be it known that I, Lonwio SEVERIN, of Hagen, T/Vestphalia, Germany, a subject of the Emperor of Germany, have invented a new and useful Device for Securing Bells, Globes, Chimneys, or the like to Lamps, of which the following is a specification.

This invention relates to a device for securing globes, balls, chimneys and lamp glasses to lamps in such manner that they are spring suspended and can easily be exchanged.

A device in accordance with this invention differs from others heretofore proposed inasmuch as there is arranged within the casing a clip comprising two resilient curved limbs adapted to engage beneath the edge of the lamp-glass to be secured to the lamp. The parts by means of which these curved limbs are secured in position, are provided with arms, pins or the like, which, like the limbs of the clip, engage beneath a projecting edge on the lamp-glass to be secured in position, and by this means firmly hold this glass, while the curved limbs can be moved apart in opposition to their spring action from the exterior of the casing to an extent sufficient to permit of the globe and like glass to be removed from the pins or the like and exchanged. The arms, pins, or the like may be made in one piece with the devices by means of which the spring clip is attached to the casing; it is however preferable that they should be adjustably arranged therein, being constructed, for instance, as set-screws.

This arrangement results in providing a simple and secure mode of attachment without any risk of the bursting of the glasses, while at the same time it insures that the suspended glasses shall be easily and quickly removable and exchangeable. Moreover. the adjustability of the set-screws renders possible not only the accurately centered suspension of the lamp-glasses but also enables the device to be adjusted for glasses of different diameters. Within the lamp casing there is preferably provided at the level of the resilient clip a groove-like depression, wherein the limbs of the clip are lodged when the glass to be suspended is being placed in position or exchanged. The resilient limbs of the clip when forced apart forinsertion or removal of the lamp glasses are completely illustrated by way of example, one construe tional form of device in accordance with this invention, Figure 1 being a side elevation thereof, partially in section, Fig. 2 a

sectional view on the line AA of Fig. 1 showing the resilient clip in its closed or looking position, Fig. 3 a sectional view on the line .A--.h. of Fig. 1 showing the resilient clip in its open position and Fig. 41- a partial section on the line BB of Fig. 3.

Referring now to the drawings :The lamp casing a to which the globe Z) is to be secured has arranged within it the two resilient curved limbs c and c of the clip, composed. of wire .or other suitable material and attached to the casing at their inner ends by suitable means, such as the screw devices (Z and CF. The two limbs c c of the clip may conveniently, as shown form portions of a continuous wire hoop. The two free ends of the clip cross each other as shown in Figs. 2 and 3 and are guided in a slot 9 formed in the casing 0, their outer ends 7 and f being bent as shown to form finger pieces or handles.

The two curved limbs c and 0 as shown in Fig. 4: when in the locking position, engage beneath the projecting edge in of the lamp-glass b and with the recess below this groove while the screw devices (Z and d by means of which the limbs and c are secured to the casing are each provided with a screw portion 70 which similarly engages beneath the projecting edge of the lamp glass and consequently assists in keeping it in position. In order to remove the lamp glass the two limbs and c of the clip are moved apart, this being effected as shown in Fig. 3 by pressing together the finger pieces or handles 7 and f and thus releasing the glass to an extent sufficient to render it easily removable from the set-screws k and 70 By suitably adjusting these screws 70 and 70 the device may be adapted for use With globes and the like of various sizes While the adjustment may at the same time be such that the globes will always be accurately centered.

The interior of the casing a is provided at the level of the limbs c and 0 With a groove m in which these limbs when in the locking position illustrated in Fig. 2 are lodged in the vicinity of their points. of attachment. J'Qhis groove has the form of a bead and serves for the reception of the handles f and 7; these limbs are moved apart to facilitate the removal. of the glass;

the limbs being then lodged completely Within the groove m as shown in Figs. 3 and 4 and being thus prevented from interfering With the removal of the globe. As Will be obvious from the drawings this arrangement enables the size of the casing to be reduced and affords a certain amount of support to the resilient limbs of the clip.

the Walls thereof, a lamp shade fastening means comprising a resilient clamping member having right angled end portions extending through the slot, said clamping member having eyes intermediate its length, set screws extending through the casing and through the eyes of the clamping member, a portion of each screw extending beyond the plane of the clamping member and en- 7 gaging the annular flange of the shade, said set screws adapted to support the rear portion of the shade and at the same time adjust the tension of the clamping member.
